【Detailed ways】

Example 1:

Referring to FIGS. 1 to 3 , the present embodiment is a highly flexible single-layer anti-needling fabric 100 , which includes a base fabric 1 , which includes a base fabric 1 , and a plurality of first anti-scratch pieces arranged at intervals on one surface of the base fabric 1 . The thorn structures 2, a plurality of second stab-proof structures 3 arranged at intervals on the other side surface of the base fabric 1, the first stab-proof structures 2 and the second stab-proof structures 3 are alternately arranged, any one of the first stab-proof structures 2 and the surrounding All the shadow areas projected by the adjacent second stab-proof structures 3 on the base fabric 1 have overlapping parts, and the overlapping parts are areas with an area greater than zero.

In this embodiment, the first stab-proof structure 2 includes a first rod-shaped support portion 21 that is fixedly attached to the base fabric 1 , a first stab-proof head portion 22 that is located on the first rod-shaped support portion 21 and is integrally formed. The two stab-proof structures 3 each include a second rod-shaped support portion 31 fixedly attached to the base fabric 1 , a second stab-proof head portion 32 located on the second rod-shaped support portion 31 and integrally formed, and the adjacent first rod There is a gap 4 between the support part 21 and the second rod-shaped support part 31 , and there is an overlapping part in the shadow area projected by the adjacent first anti-stab head 22 and the second anti-stab head 32 on the base fabric 1 .

Viewed from the projection direction of the base fabric 1 , the gap between two adjacent first stab-proof heads 22 is filled by the second stab-proof structure 3 .

The upper surface of the first stab-proof head 22 or the second stab-proof head 32 is a convex curved surface structure. The bottom projection surfaces of the first stab-proof head 22 and the second stab-proof head 32 are circular, oval, or polygonal, in this embodiment, a circle, and the diameter of the circle is larger than that of the first rod-shaped support part 21 and the diameter of the second rod-shaped support part 31 . The diameter of the projected circle at the bottom of the first stab-proof head 22 and the second stab-proof head 32 is 0.2-10 mm, and the diameter of the first rod-shaped support part 21 and the second rod-shaped support part 31 is 0.2-5 mm. The height is 0.1 to 5mm.

The maximum span of the outer contours of the first stab-proof structure 2 and the second stab-proof structure 3 is 0.2-10 mm, and the overall height thereof is 0.2-10 mm.

By defining the size of the first stab-proof structure 2 and the second stab-proof structure 3 , the distance between two adjacent first stab-proof structures 2 and the distance between two adjacent second stab-proof structures 3 can be defined. The distance between them ensures the flexibility of the fabric on the basis of ensuring that the entire surface of the fabric is covered by the stab-proof structure.

Since the upper surface of the stab-proof structure on the upper surface of the base fabric 1 is a curved surface structure, although the curved surface structure has a good stab-proof effect in terms of strength and stab-proof, and the overall size of the stab-proof structure in this embodiment is very large Small, there are great difficulties in the production process, and the use of the curved surface structure has a higher success rate in the production and molding. However, the curved surface structure has certain guiding properties for the needle, and there is a gap between the two adjacent stab-proof structures, so in order to prevent the needle from being directly guided into the surface of the base cloth 1 when the needle pierces the surface of the stab-proof structure, this embodiment An annular groove structure 23 is provided on the upper surface of the first stab-proof head 22 , and an annular protrusion blocking structure 33 is disposed on the side surface of the second stab-proof head 32 close to the base fabric 1 , through which the annular groove structure 23 The needle can be guided into it under the guidance of the curved surface to block the path of the needle entering the base fabric. When the fabric is bent at a large angle, the needle may be inserted obliquely through the base fabric 1. At this time, the annular protrusion blocking structure 33 can Block the forward direction of the needle.

The shadow area projected by the first rod-shaped support portion 21 and the second stab-proof head portion 32 on the base fabric 1 has an overlapping portion, and the overlapping portion may be a point or an area with an area greater than zero. The larger the area of the overlapping portion, the better the protection performance against the larger the bending angle of the fabric.

In this embodiment, the stab-proof structure is arranged on both sides of a single layer, and the stab-proof structures on both sides are arranged at intervals, while the stab-proof structures of different surface layers are arranged in a staggered manner. , and the whole fabric is covered by the stab-proof structure, which is safe and reliable; the stab-proof structure on one side is arranged at intervals, which greatly improves the flexibility of the fabric, and at the same time meets the requirements of high flexibility and stab resistance.
